REMOVING THE SMELL OF CAT URINE FROM CARPET
Carpet has a reputation of being particularly difficult to deodorize. But it doesn't have to be. Follow the simple steps below to eliminate lingering odors.
Get some white vinegar (the old, plain kind will do), hydrogen peroxide, liquid hand soap, and baking soda.
If the spot is dry, proceed to step 3. Otherwise, blot the area (don't rub!) with a paper towel to absorb as much moisture as you can.
Mix equal parts water to vinegar and pour the mixture over the affected area to saturate and let it dry.
Liberally sprinkle the baking soda over the spot.
Then stir up a mixture of hydrogen peroxide and dish liquid (four parts hydrogen peroxide to one part detergent) and lightly rub the mixture onto the area. Use a brush (old toothbrushes work wonders), gloved fingers, or whatever else you have on hand to get the job done.
After it dries, vacuum the area. If the smell remains, repeat the process.
